In an unprecedented agreement between Major League Baseball and union officials, suspended Giants outfielder Melky Cabrera will be ruled ineligible to win the 2012 NL batting title, sources told CSNBayArea.com.

Cabrera asked to be removed from consideration on Wednesday, when his representatives sent a letter to union officials. The Players’ Association worked out a one-time amendment to Rule 10.22(a) with MLB officials on Thursday, one day after Commissioner Bud Selig said publicly that he was not likely to take action on the matter.

A “one-time amendment” to the rule is a curious phrase. Rather Orwellian, actually. What it is a decision to just ignore a rule because baseball and/or Melky Cabrera or whoever initiated this decision didn’t like the repercussions of that rule.

I presume this will make a lot of people happy because no one was comfortable seeing Melky Cabrera win the batting title. But it also opens the door for all manner of messing around with the rules in the future when they don’t produce results to someone’s liking. Which is exactly the kind of arbitrary thing having rules is supposed to prevent.

I also love how Melky “asked to be removed from consideration” for the batting average title. Quick: Adam Dunn! Call the league and ask to be taken out of consideration for the strikeout title.
